FILTER-SEPARATOR Russian patent published in 2011 - IPC B01D29/11 B30B9/26 

FIELD: process engineering.

SUBSTANCE: invention relates to filtration, in particular, to band filter press to be used in chemical and other industries for separation of liquid-solid suspensions, primarily, for mechanical dehydration of sediments of municipal, household, natural and industrial effluents. Filter press incorporates squeezing rollers interacting with a sleeve made from filtration fabric to squeeze fluid from suspension flowing in the sleeve. Said sleeve is fixed while squeezing rollers displace along the sleeve section while spring-loaded clamping spring is arranged opposite said section its shape following the clamping rollers. Sleeve section on the suspension feed side is arranged vertically and above the sleeve section interacting with clamping rollers.

EFFECT: simple and reliable design, efficient dehydration.
